Objective: To present a list of key points for good Temporomandibular Disorders (TMDs) clinical practice on behalf of the International Network for Orofacial Pain and Related Disorders Methodology (INfORM) group of the International Association for Dental, Oral and Craniofacial Research (IADR).

Methods: An open working group discussion was held at the IADR General Session in New Orleans (March 2024), where members of the INfORM group finalized the proposal of a list of 10 key points.

Results: The key points covered knowledge on the etiology, diagnosis, and treatment.

The Association Between the Central Sensitisation Inventory and Temporomandibular Disorders Is Confounded by Migraine, Depression, Widespread Pain and Parafunction. A Cross-Sectional Telehealth Study.

Background: Temporomandibular disorders (TMDs) are conditions that involve the temporomandibular joints, masticatory muscles, and associated tissues, causing orofacial pain. Central sensitisation (CS) is a relevant part of the TMD pathophysiology. Migraine, psychological aspects, parafunctional oral habits and widespread pain are commonly associated with both TMD and CS and could confound the association between them.

Constructing the brief diagnostic criteria for temporomandibular disorders (bDC/TMD) for field testing.

Background: Despite advances in temporomandibular disorders' (TMDs) diagnosis, the diagnostic process continues to be problematic in non-specialist settings.

Objective: To complete a Delphi process to shorten the Diagnostic Criteria for TMD (DC/TMD) to a brief DC/TMD (bDC/TMD) for expedient clinical diagnosis and initial management.

Methods: An international Delphi panel was created with 23 clinicians representing major specialities, general dentistry and related fields.

Patients' experiences of temporomandibular disorders and related treatment.

Background: Temporomandibular disorders (TMD) are common and therefore managed by dentists on a daily basis. However, patients with TMD consistently go undetected and therefore untreated in dentistry. The reasons for these shortcomings have not been fully explored, specifically with regard to patients' perspectives.

Incidence of interappointment emergencies in multiple-visit root canal treatments performed with or without intracanal medicament by undergraduate students.

Objectives: This retrospective cohort study examined the incidence of interappointment emergencies during multiple-visit molar root canal treatments conducted by undergraduate students. Treatments performed without the use of intracanal medicament were compared to treatments that incorporated calcium hydroxide as an intracanal medicament.

Materials And Methods: Interappointment emergencies, defined as instances of pain or swelling that required the patient to make an unscheduled follow-up visit, were recorded for up to 2 months after the intervention.

Psychosocial factors associated with pain outcomes in patients with painful temporomandibular disorders and headaches.

The objective of this study was to assess the association between psychosocial factors (in terms of anxiety, somatization, depression, and optimism) and pain (in terms of headache pain intensity and pain-related disability), in patients with a painful temporomandibular disorder (TMD) and one of the following headache types: migraine, tension-type headache (TTH), or headache attributed to TMD, corrected for the influence of bruxism. A retrospective study was conducted at an orofacial pain and dysfunction (OPD) clinic. Inclusion criteria were painful TMD, with migraine, TTH, and/or headache attributed to TMD.

Prevalence of painful temporomandibular disorders, awake bruxism and sleep bruxism among patients with severe post-traumatic stress disorder.

Background: Post-traumatic stress disorder (PTSD) is associated with painful temporomandibular disorder (TMD) and may be part of the aetiology of awake bruxism (AB) and sleep bruxism (SB). Investigating the associations between PTSD symptoms on the one hand, and painful TMD, AB and SB on the other, can help tailoring treatment to the needs of this patient group.

Objectives: The aim of this study was to investigate the associations between PTSD symptoms and painful TMD, AB and SB among patients with PTSD, focusing on prevalence, symptom severity and the influence of trauma history on the presence of painful TMD, AB and SB.

The additional value of e-Health for patients with a temporomandibular disorder: a mixed methods study on the perspectives of orofacial physical therapists and patients.

Purpose: To assess the experience and perceived added value of an e-Health application during the physical therapy treatment of patients with temporomandibular disorders (TMD).

Materials And Methods: A mixed-methods study including semi-structured interviews was performed with orofacial physical therapists (OPTs) and with TMD patients regarding their experience using an e-Health application, Physitrack. The modified telemedicine satisfaction and usefulness questionnaire and pain intensity score before and after treatment were collected from the patients.

The association between myofascial orofacial pain with and without referral and widespread pain.

Objectives: Pain referral on palpation has been suggested to be a clinical sign of central sensitization potentially associated with widespread pain conditions. Our aim was to evaluate if myofascial pain with referral is a better predictor for widespread pain when compared to no pain or local myofascial pain.

Materials And Methods: Individuals at the Public Dental services in Västerbotten, Sweden, were randomly invited based on their answers to three screening questions for temporomandibular disorders (TMD).

Translation and cross-cultural adaptation of the Headache Screening Questionnaire into Brazilian Portuguese.

Background: The Headache Screening Questionnaire (HSQ) was created and validated to enable health professionals to screen for migraine and tension-type headaches.

Objectives: The objective of this study was to translate and cross-culturally adapt the HSQ, creating the Brazilian version of the HSQ (HSQ-BR).

Design: This was a cross-sectional study.

The effect of singing on pain and psychological well-being in a patient population with pain-related temporomandibular disorders.

Background: Even though singing is regarded as potential jaw-overuse behaviour, the actual evidence that underlines the idea of singing as a predisposing factor for pain-related temporomandibular disorders (TMD) is very limited.

Objectives: The objectives were to examine if a dose-response relationship exists between the frequency of singing and TMD pain intensity, and if singing is associated with psychological well-being.

Methods: The records of 1467 adult patients with functionally aggravated TMD pain were examined.

Fear of Movement and Catastrophizing in Participants with Temporomandibular Disorders.

Aims: To assess differences in catastrophizing and kinesiophobia in relation to areas of pain and somatic symptoms among participants with temporomandibular disorders (TMDs) and controls.

Methods: In total, 401 participants (333 women, 68 men, mean age: 45.8 years) in the TMJ Impact Project were examined in accordance with the Diagnostic Criteria for TMD, including clinical examination (Axis I) and psychosocial assessment (Axis II) augmented with imaging of the temporomandibular joint (TMJ).

Reduction of Somatic Tinnitus Severity is Mediated by Improvement of Temporomandibular Disorders.

Background: Successful orofacial treatment can reduce tinnitus severity in patients with somatic tinnitus (ST). However, it is still unclear to what extent the degree of reduction in temporomandibular disorders (TMD) actually contributes to the decrease in tinnitus severity after orofacial treatment. Therefore, the aim of this study was to analyze the mediating effect of reduction in TMD pain on the improvement of tinnitus severity after multidisciplinary orofacial treatment.

The change in self-efficacy of novice dentists in Endodontics within the first year following graduation from Aarhus University or the Academic Centre for Dentistry Amsterdam.

Aim: To understand whether the self-efficacy of novice dentists in Endodontics changes within the first year following their graduation, and to reveal factors related to a possible change.

Methodology: Data were obtained from dental graduates from Aarhus University, Denmark or from the Academic Centre for Dentistry Amsterdam, the Netherlands. The 60 participants filled out the Endodontic General Self-Efficacy Scale questionnaire close to their graduation (baseline) and 1 year following their graduation (follow-up).

Even mild catastrophic thinking is related to pain intensity in individuals with painful temporomandibular disorders.

Aims: Temporomandibular disorders (TMD) are often associated with psychological comorbidities. One such comorbidity is pain catastrophising, that is, exaggeration of negative consequences of a painful event. The aim was to investigate catastrophising in individuals with painful TMD compared to controls and the association between catastrophising and pain intensity, number of pain sites and functional limitations.

Oral health-related quality of life in patients with early rheumatoid arthritis is associated with periodontal inflammation and painful temporomandibular disorders: a cross-sectional study.

Objectives: To evaluate oral health-related quality of life (OHRQoL) in early rheumatoid arthritis (ERA) patients and individuals at risk of rheumatoid arthritis (RA) compared to healthy controls, and to explore possible associated factors.

Materials And Methods: Fifty ERA patients, 50 at-risk individuals, and 50 age and gender matched healthy controls were recruited. OHRQoL (Oral Health Impact Profile-14 (OHIP-14)); number of decayed, missing, and filled teeth (DMFT); denture use; periodontal inflamed surface area (PISA); xerostomia (xerostomia inventory (XI)); and possible TMD (-pain) diagnoses were recorded.

Conceptualizing the clinical decision-making process in managing temporomandibular disorders: A qualitative study.

Management of patients with temporomandibular disorders (TMD) appears to be more challenging than for other dental conditions. This study aimed to explore the decision-making process in TMD management, and thereby to conceptualize the decision-making process in dentistry. Individual semi-structured interviews were conducted during 2018 and 2019 with a purposive sample of 22 general dental practitioners from the Public Dental Healthcare Services and private practices in the Region of Västerbotten, Northern Sweden.

Association between polysomnographic parameters of sleep bruxism and attrition-type tooth wear.

Background: Clinically, sleep bruxism is considered to be associated with the presence of tooth wear, but strong evidence is still lacking.

Objective: To examine whether an association exists between polysomnographic parameters, recorded from patients with possible sleep bruxism and tooth wear.

Methods: Sixty-three possible sleep bruxers (19 males and 44 females, mean ± SD age = 38.

Temporomandibular disorders in patients with early rheumatoid arthritis and at-risk individuals in the Dutch population: a cross-sectional study.

Objective: To evaluate the prevalence of temporomandibular disorders (TMD) in patients with early rheumatoid arthritis (ERA) and individuals at-risk of RA.

Methods: 150 participants were recruited in three groups (50 per group): (1) patients with ERA (2010 EULAR criteria) (2) at-risk individuals and (3) healthy controls. All participants were tested for seropositivity of rheumatoid factor and anticitrullinated protein antibodies.
